Use method of drying device for clammy ore product sample

Abstract

The invention relates to a use method of a drying device for a clammy ore product sample. The use method comprises following steps of: starting a cycloidal reducer, opening a barrel cover and adding ato-be-tested clammy ore product sample to a stainless steel inner cylinder; closing the barrel cover, starting a dehumidifying fan, a heating fan and a heater, pushing, by a spiral auger, the sampleto an agitating rod to agitate, sending hot air into the sample by the heating fan, pumping out moisture in the stainless steel inner cylinder by the dehumidifying fan, and blowing, by the heater, moisture into the sample in the stainless steel inner cylinder to dry and agitate; starting a motor, turning off the heater, and reversely starting the cycloidal reducer, and pushing mixed material to aposition of a square discharge port I by the spiral auger; turning a handwheel, extracting an insertion board from an insertion board port, and discharging the sample into an auger assembly dischargetube; and driving, by the motor, auger blades with shafts to roughly crush the entering sample and transfer the roughly crushed sample to a crusher feed port of a next procedure. The method realizes an integrated structure with functions of agitating, drying, and crushing, and realizes complete automation.

Description

technical field [0001] The invention relates to a method for using a sticky-wet mineral product sample preparation and drying device, which is a device and a process method for preparing mineral product sample preparation and drying with high humidity, high viscosity and uneven particle size distribution. Background technique [0002] At present, with the increasing metal smelting technology in recent years, mineral products of different grades can be used extremely well. [0003] At this stage, various metal processing units have imported a large number of low-grade, high-humidity, and high-viscosity mineral products from the international market. The current sample preparation and analysis methods for such mineral products still use the traditional model. After the samples are collected, they are mixed and divided. Analytical samples were obtained by static drying. [0004] In our daily work, we found that the current sample preparation process has the following technical...

AI Technical Summary

Problems solved by technology

[0006] 2. The drying box is heated by heat conduction, the heating efficiency is not high, and it is difficult to carry out effective heat exchange in a relatively closed environment

[0007] 3. In order to improve the drying efficiency, we can only increase the drying air volume or increase the temperature, which will inevitably increase the energy consumption of the blast and waste energy

[0008] 4. The drying process of the sample is slow, and the process of manual stirring and turning is required to speed up the drying, which not only wastes manpower but also easily causes safety accidents

[0009] 5. After drying, the samples are easy to form condensed soil lumps, with high hardness and large particle size, which cannot be directly entered into the crusher, and rough crushing is still required manually.
